LetteraPatent No. 92,459, dated July 13, 1869.

IMPRovED WASHING-MACHINE.

The Schedule referred to in these Letters VPatent: and making'parl: of the Same- To all whom it may concern .Be it known that I, O. H. KNOX, of Mount Pleasant, in the county of Henry, and" State of Iowa, have invented au Improvement-in Washing-Machines; and I do hereby declare that the following is a full, clear, and exact description ot' the lconstruction and operation of the same, reference being had to thev accompanying drawings, and letters marked theieon,in

which- Figure l is a sectional elevation of my invention. Figure 2, a broken elevation of the central journal, showing the right and left-hand screw-threads.

Figure 3, 'a perspective View of the washer and its attachment, detached from the other parts of themachine.

The object of the present invention is more especially to improve the washing-machine patented `by me, on the 22d January, 1867 and Its nature consists in the novel means employed to secure the washer tothe centre' journal, whereby the machine can be put together with much lessdiiiieulty,

and the'washer held iirmly in 4place, and so as to be removed when required.

To enable others to fully comprehend the construc-A tion and operation of my invention, I have marked corresponding. parts of the same with similar letters, and will now give a detailed description..

A represents a common washing-box, which is made of wood, and similarly tothe b'ox used in thepatent above referred to; and

B B show the two-part lid, to which the gearing-D O and metal frame K are attached, said gearing beingV the same as shown Vin said patent.-

and at the same time permit the latter to be'readily removed when it becomes necessary to lift the washer H ont of the box A, which operation is frequently required.

The journal E, as now arranged, can only be rcmoved from t-he top of the box, and hy being drawn through its bearing F; and to provide for securing and removing the washer H, a left-hand screw, m, is out on the journal, as shown at fig. 2, and a metal clamp, O, having a corresponding screw-thread, is turned thereon said clamp havinglngs, J J, projecting downward, and into depressions made in the top ofthe washer.

A right-hand-screw-thread is cut on the lower end of the journal, and a nut, K, with a corresponding screwthread, turned thereon, thus holding said washer firmly between the clamp and nut.

, This arrangement is very simple, yet important, for the reason that hot water is generally'used in this kind of a machine, and if some permanent means are not employed, the washer will become loosened ordetached, as there is a great strain on the pins I when giving the clothes. in the box A reciprocating rotary motion.

The operation of the machine is simple, and generally well understood,` requiring only that the lever Rr should be grasped with the hand and moved back and forth, so as to give the pinion D a suitable motion.

Having thus described my invention, What I claim, and desire to secure by Letters Patent, is The combination of the washer H with the clamp G, journal E, nut K,^and pinion D,`said clamp and nut vbeing arranged to turn on iight and leftehand screws, and clamp the washer between them, as speciiied and shown.
